    For (-3, 2) : 2 > 5 (-3) + 2; 2 > - 15 + 2; 2 > - 13 (i. e. not correct)

    for (-1, 3) : 2 > 5 (-1) + 2; 2 > - 5 + 2; 2 > - 3 (i. e. not correct)

    for (0, 2) : 2 = 5 (0) + 2; 2 = 0 + 2; 2 = 2 (i. e. not correct)

    for (1, 2) : 2 < 5 (1) + 2; 2 <5 + 2; 2 1/2 (1) + 1; 2> 1/2 + 1; 2 > 3/2 (i. e. correct)

    for (2, - 1) : - 1 < 5 (2) + 2; - 1 < 10 + 2; - 1 < 12 (i. e. correct) : - 1 < 1/2 (2) + 1; - 1 < 1 + 1; - 1 < 2 (i. e. not correct)

    for (2, 2) : 2 < 5 (2) + 2; 2 < 10 + 2; 2 < 12 (i. e. correct) : 2 = 1/2 (2) + 1; 2 = 1 + 1; 2 = 2 (i. e. not correct)

    Therefore, both ineaqualities are tru for only the ordered pair (1, 2)
